You don't need anything on Lexan to keep it from shattering. It won't. Plexi on the other hand can be as dangerous or even more dangerous than glass. Don't use it!

Can you use any polycarbonate sheet or does it have to be Lexan.

Lexan is a brand name for one company's polycarbonate. What you're looking for is polycarbonate. The best type for our purposes is Margard or an equivalent which is scratch resistant, probably because of a coating.

My apoligies, I should have been clearer. What I am thinking of is tinting the lexan, the sheet that I have is clear, and I thought about applying tint or spraying the lexan just for pure cosmetic purposes.

Also, what about using pop rivets to hold the lexan in, or would it be better to use screw and nuts?

Properly sized pop rivets with backing washers should provide adequate retention and dont think they will be a problem with the inspectors. I dont really think they are better, just an alternative.

I have used rivets on my windshield, along with the 200mph tabs and have had zero problems or questions from inspectors about their use.

Note:
I use a 1/4" Lexan type polycarbonate (Bayer Makrolon) and recommend a minimum of 1/4" for the windshield.
Markrolon can be purchased tinted in various degrees and colors (and likely others however I dont know). You may be better off buying a pre tinted piece (*this is your call however). I am really happy with my pre-tinted plastic.

If you need any tips for making the windshield send me a mail.

My choice would be to use 10/32 buttonhead (or countersunk) fasteners with nylok nuts (and washers). If you need to remove the windshield (or other-located window), you don't risk "wallering out"  :-D the holes in either the lexan or the frame, as you do when removing rivets inexpertly  with a drill.    vic
